The ICC1324 is a 4th generation charge controller for use in EV applications. Its PCB design makes installation in charging stations easier and more flexible. With its integrated power supply and latest hardware design, even more functions are combined in a minimum of space.

Intended for use by OEMs and EV charge station designers and manufacturers, the ICC1324 was designed for use in public, semi-public and private charging stations. Besides the already known safety features such as 6 mA DC residual current detection, weld check, monitoring of the PE conductor and a charging plug emergency opener, the key functions also include Powerline Communication (PLC) according to ISO 15118 for the implementation of plug & charge as well as dynamic load management (DLM). This feature enables simultaneous charging of up to 250 electric vehicles.

The ICC1324 is smart-grid-capable through OCPP 1.5 and 1.6 (JSON and SOAP). In addition, the charge controller has WiFi, a 4G modem and Ethernet ports and supports all important communication protocols such as EEBUS, SMA SEMP and Modbus TCP.

The charge controller software can be updated (information on cybersecurity). This makes the ICC1324 future-proof. Updates (typically quarterly) can be easily installed via USB, Ethernet or over-the-air (OTA).
